I'll be honest, I'm drawing a blank on where I heard that about dev negative feedback towards GP. Could have been someone's podcast rather than a dev? I was thinking things like PS5 getting extra shit like RE village demo, but now that I think about it, that could just be one of the things Sony paid for, exclusive demo to help with mindshare conflating RE and PS etc.
I myself don't really see the point in timed exclusivity. Unless you need to play a game on day 1, you can just wait. Especially if one is conditioned to wait (paying GP in the mean time), in the hopes that something comes to PC/GP at a later date. That's another reason why I don't really like PC ports. If gamers are being conditioned to wait for PC or GP, they're less likely to purchase at all, especially at full price when Sony are trying to establish a new higher day 1 price at the same time. Eventually, how do you plan to successfully sell your next console to the masses? It won't be exclusive games, that people just wait on a PC port, or timed exclusive games/content, where people wait for eventual GP drop.
